UNITED STATES PATENT OFFICE.

CHARLES G. ENGLE, OF JACKSON, MICHIGAN.

PADLOCK.

Application filed December 5, 1919.

To all lwhom t may concern:

Be it known that I, CHARLES G. ENGLE, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Padlocks, of which the following is a specification.

This invention relates to a padlock and has for its primary object the production of a padlock having a shackle with a tortuous guide way so that only those knowing the configuration of the said guide way will be able to operate the lock.

Another object of the invention is the production of a link or latch which will swing transversely of the casing and move in the tortuous guide way so as to allow the shackle to be in an opened or locked position.

A still further object of the padlock is to provide means whereby only those who are familiar with the configuration of the guide way provided in the shackle will be able to intelligently operate the lock.

With these and other objects in view, this invention consists of certain novel combinations, arrangements and constructions as will be hereinafter more fully described.

In the drawing,

Figure 1 is a front elevation of my invention.

Fig. 2 is a vertical sectionof my invention showing same in an open position and Fig. 3 is a section taken on lines 3--3 of Fig. 1 looking in the direction of the arrows.

By referring to the accompanying drawv ing by numerals it will be seen that my lock consists of two principal. parts, namely the casing 10 and the shackle 13. The casing 10 is provided with a closed bottom and the top 21 which has the opening 11 adjacent the edges of the casing. The shackle 13 consists of the usual book portion and the body portion 12. This body portion 12 is substantially rectangular in shape and is substanY tially of the same width as the casing 10 but its length. is substantially shorter.

Provided in the body portion 12 is the elongated vertical guide way 18 which is situated adjacent the opening 11 and runs parallel with the edge of the body portion 12. Adjacent the other opening 11 there is provided the vertical guide way 19 which is substantially shorter than the guide way 1S. The guide way 19 enters into the horizontal guide way 20 which in turn enters into a Specification of Letters Yatent.

short vertical guide way 21. The guide way 21 terminates in the curved guide way portion 22.

The link 16 is pivoted adjacent the bottom of the case by means of the rivet 17 and has the cross piece 20 which is adapted to run in the various guide ways. A leaf spring let is equipped upon the bottom of the casing l() and is held thereon by means of the rivet.

The body portion 12 of the shackle is adapted to slide in the guide ways formed by the wire 22 which are placed in the corners of the casing 10 as is clearly shown. in Fig. 3. By referring to Figs. 1 and2 it will be seen that when the body portion is adjacent the top 21 of the casing 10 the shackle is in what might be called the open position and when the body portion 12 is adja cent the bottom of the casing, the shackle 13 is in the locked position.

To operate this padlock when same is in an open position as shown in Fig. 2 it will be seen that the casing 10 will be lifted so that the body portion 12 will slide downwardly toward the bottom of the casing. In the above movement of the casing it will be seen that the cross piece 2O of the link will ride in the guide way 18 to the top of the body portion 12. When the cross piece 20 has arrived in this position it will be seen that the casing should be swung slightly to the right and thereby allow gravity to work upon the link thereby causing it to swing over to the left of the body portion so as to come into engagement with the guide way 1 9. When the cross piece 2O is in the last mentioned position it will be seen that by pulling downwardly upon the casing 10 the cross piece 2() will ride in the guide way 19 and enter the guide way 20. By now tilting the casing to the left gravity will cause the link to swing to the right7 thereby passing through the guide way 20 so that by further lifting upon the casing 10 the link or cross piece 20 will ride in the guide way 21 and by slightly swinging the casing to the right, the cross piece will take the position in the guide way 21 as is shown in dotted lines in Fig. 1 of the drawing. It is obvious that to Uunlock the padlock the process just described will be reversed whereby the cross piece 20 will be in the position shown in Fig. 2 of the drawing. The purpose of the leaf sp1-ing 14 is to cause suflicient friction between the cross piece 20 and the guide way 22 so that those unfamiliar with the mechanism of the lock will not be able to accidentally operate same.

The above description of course relates to the preferred form of my invention and it should of course be understood that I do not intend to limit myself to the particular guide way shown and that I may make such modifications and changes as come within the scope of the appended claims.

Having thus described my invention, what I claim as new is l. A padlock of the class described comprising a casing and a shackle, said shackle having a body portion provided with a tortuous guide way, locking means for riding in said guide Way. y

2. A padlock of the class described comprising -a casing and a shackle, a link pivotally mounted in said casing, and means provided whereby said link will hold said shackle in a locked or open position by p swinging transversely of said casing.

. 3. A padlock of the class described comprising a casing and a shackle, said shackle having a substantially rectangular shaped body portion, said body portion provided with an elongated vertical guide way, said elongated guide way running parallel with the edge of said body portion, and situated adjacent said edge, a tortuous guide way situated adjacent the other edge of said body portion, a link pivotally mounted within said casing and adapted to swing transversely thereof, a cross piece provided upon the upper'or free end of said link so as to run in said guide way and means for pre venting said link from being accidentally displaced when in a locked position.

4L. A padlock of the class described comprising a casing and a shackle, said shackle having a body portion within the casing and provided with a guide way, a link pivotally mounted within said casing and provided at its top with a cross piece adapted to ride in said guide way.

5. A padlock of the class described comprising a casing and a shackle, said shackle having a body portion provided with a guide way, a link pivotally mounted within said casing and provided at its top with a cross piece adapted to ride in said guide way, and means for preventing the movement of said link when the same is in a locked position.

6. A padlock of the class described comprising a casing and a shackle, said shackle having a substantially `rectangular shaped body portion, said body portion provided with an elongated guide way, said elongated guide way running parallel with the edge of said body portion and situated adj aeent said edge, a tortuous guide way situated adjacent the other edge of said body portion, a link pivotally mounted within said casing and adapted to swing transversely thereof, a cross piece provided upon the upper or 'free end of said link so as to run in said guide way, a leaf spring ixedly attached at one end to the bottom of said casing so as to allow its free end to bear upwardly upon the bottom of said body portion of said shackle, thus preventing accidental displacement ci said link when same is in a locked position.

In testimony whereof I aliix my signature in presence of two witnesses.

CHARLES G. ENGLE.
